Product Description:

The MAC041A-0-FS-4-E/050-B-0/WI673LV is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It interfaces with analog velocity and current amplifiers to generate precise, closed-loop rotary motion in drilling heads, pick-and-place actuators, and auxiliary conveyor drives. By supplying instantaneous torque that tracks the command signal from the analog controller, the motor supports repeatable positioning tasks and synchronized line operation in industrial automation lines. Its feedback signals allow the external amplifier to correct speed and position deviations during changing load conditions.

For mechanical integration, frame size 041 identifies the stator outside diameter, and length code A indicates the shorter housing length. Heat produced by copper losses is removed through natural convection, so the housing fins must remain unobstructed for stable temperature control. The embedded stator winding marked FS sets the phase resistance, inductance, and voltage constant that must match the companion analog drive. Incoming three-phase power is routed through a single screw-locking connector installed at connector on side B, which helps keep power leads separated from feedback cabling in narrow cabinet layouts. This layout also simplifies right-angle mounting where enclosure depth is limited.

The motor has no holding brake, so any vertical or overhung load must be secured by an external brake or gear lock when power is removed. Classified as a motor for analog drives, the unit provides feedback signals that legacy current-loop regulators can process directly. Shaft position is monitored by an incremental encoder with standard mounting, and the auxiliary feedback arrangement uses tacho feedback with an incremental or absolute encoder to support higher-resolution position sensing or tachometer-based speed loops within the same mechanical envelope.
